Sedum plant named ‘Rosetta’

ABSTRACT

A new and distinct hybrid of  Sedum  plant substantially as shown and described, with blue green leaves, spring growth with opening leaves that look like cabbages, cream colored flowers in medium inflorescences, a medium, upright, arching habit, and excellent vigor.

Botanical denomination: Sedum telephium (Syn. Hylotelephium telephium).

Variety designation: ‘Rosetta’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedumtelephium and given the cultivar name of ‘Rosetta’. Sedum is in thefamily Crassulaceae. The new cultivar is part of a planned breedingprogram to make short, compact, multicrown plants. The new cultivaroriginated from a controlled cross of a proprietary seedlings, 29-5, asthe seed parent, and 29-6, as the pollen parent.

Compared to the seed parent, Sedum 29-5, the new cultivar is shorter andhas much better quality foliage. Compared to the pollen parent, Sedum29-6, the new cultivar has a smaller, bluer green leaves, and a betterhabit.

Compared to Sedum ‘Hab Gray’, an unpatented plant, the new variety hassmaller leaves, shorter internodes, and is more upright.

This new and unique Sedum is distinguished by:

-   -   1. blue green leaves,    -   2. spring growth with opening leaves that look like cabbages,    -   3. cream colored flowers in medium inflorescences,    -   4. a medium, upright, arching habit, and    -   5. excellent vigor.

This new cultivar has been reproduced only by asexual propagation(division and tissue culture). Each of the progeny exhibits identicalcharacteristics to the original plant. Asexual propagation by divisionand tissue culture using standard micropropagation techniques withterminal and lateral shoots, as done in Canby, Oreg., shows that theforegoing characteristics and distinctions come true to form and areestablished and transmitted through succeeding propagations. The presentinvention has not been evaluated under all possible environmentalconditions. The phenotype may vary with variations in environmentwithout a change in the genotype of the plant.
